Metabolism in Living Cells Quiz

What is the definition of metabolism in a living cell?

• The sum of all chemical processes in a living cell

• The breakdown of complex molecules only

• The synthesis of simple molecules only

• The release of energy only

Which type of reaction requires energy to synthesize complex molecules from simple molecules?

• Catabolism

• Anabolism

• Metabolism

• Respiration

Which process involves the release of energy by breaking down complex molecules to simpler ones?

• Anabolism

• Catabolism

• Photosynthesis

• Metabolism

Anabolism and catabolism are related to metabolism in a living cell in which of the following ways?

• Both are types of metabolic reactions; anabolism builds complex molecules using energy, while catabolism breaks down complex molecules releasing energy.

• Anabolism and catabolism are unrelated to metabolism.

• Only catabolism is part of metabolism.

• Only anabolism is part of metabolism.

Which process in metabolism breaks down larger molecules into smaller molecules and releases energy?

• Catabolism

• Anabolism

• Photosynthesis

• Fermentation

What is the process called that builds larger molecules from smaller molecules in metabolism?

• Anabolism

• Catabolism

• Respiration

• Hydrolysis

Energy is involved in the metabolic processes of catabolism and anabolism in the following way:

• Catabolism releases energy, while anabolism requires energy.

• Anabolism releases energy, while catabolism requires energy.

• Both catabolism and anabolism release energy.

• Neither catabolism nor anabolism involve energy.

Which term describes a collection of biochemical reactions that occur simultaneously in a cell?

• Metabolism

• Photosynthesis

• Respiration

• Fermentation

In a metabolic pathway, what are A and B referred to as?

• Reactants or precursors

• Products

• Enzymes

• Intermediates

What role do enzymes play in metabolic pathways?

• They catalyze each reaction

• They are products of the pathway

• They are reactants

• They are intermediates
